| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We tried to grow (001) oriented L10-MnGa films on thermally oxidized Si substrate, and compared their structures and magnetic properties with those of (001) oriented L10-MnGa grown on MgO(001). Moreover, local ion irradiation on the MnGa on Si substrate was used to fabricate magnetically patterned MnGa.. The MnGa grown on Si substrate exhibited a saturation magnetization of 140 emu/cc, which is around 1/3 of that grown on MgO(001), and showed perpendicular magnetic anisotropy. The surface roughness Ra was confirmed to be 1.2 nm, and it was confirmed that the magnetism of the MnGa was transferred from ferromagnetic to paramagnetic by 30 keV Kr ion dose of 2 × 1014 ions/cm2. Furthermore, we confirmed the magnetically patterned structure with a pitch size down to 150 nm by the local ion irradiation on MnGa on Si substrate. | |
